Coil winding machine and coil winding method thereof

Abstract

A coil winding machine is adapted for winding a conductive flat wire onto an iron core. The coil winding machine includes a base, a tension mechanism mounted on the base and adapted for delivering the flat wire and providing tension to the flat wire, a rotary mechanism mounted on the base and including a core base that is rotatable and that is adapted to be mounted with the iron core, and at least one clamping mechanism mounted on the base, being co-rotatable with the core base, and operable for abutting the flat wire tightly against the iron core. A tension provided by the tension mechanism, a pressure provided by the clamping mechanism, and a rotational speed of the core base correspond to one another such that rotation of the core base and the at least one clamping mechanism winds the flat wire onto the iron core.

What is claimed is: 
     
         1 . A coil winding machine adapted for winding a conductive flat wire onto an iron core, said coil winding machine comprising:
 a base;   a tension mechanism mounted on said base, and adapted for delivering the flat wire and providing tension to the flat wire;   a rotary mechanism mounted on said base, and including a core base that is rotatable and that is adapted to be mounted with the iron core; and   at least one clamping mechanism mounted on said base, being co-rotatable with said core base, and operable for abutting the flat wire tightly against the iron core;   wherein a tension provided by said tension mechanism, a pressure provided by said clamping mechanism, and a rotational speed of said core base correspond to one another such that rotation of said core base and said at least one clamping mechanism winds the flat wire onto the iron core.   
     
     
         2 . The coil winding machine as claimed in  claim 1 , wherein said at least one clamping mechanism includes two clamping mechanisms that are disposed respectively at opposite sides of said core base and that are operable for alternately abutting the flat wire tightly against the iron core. 
     
     
         3 . The coil winding machine as claimed in  claim 2 , wherein said tension mechanism includes:
 a delivering plate that is mounted on said base for delivering the flat wire; and   a driving member that is connected to said delivering plate and that is vertically movable for downwardly pushing the flat wire.   
     
     
         4 . The coil winding machine as claimed in  claim 1 , wherein:
 said rotary mechanism includes a servomotor mounted on said base, and a claw member connected to said servomotor and grips said core base; and   said servomotor is operable for driving rotation of said claw member and said core base.   
     
     
         5 . The coil winding machine as claimed in  claim 1 , wherein:
 said at least one clamping mechanism includes a clamping plate that is operable for abutting the flat wire tightly against the iron core; and   said clamping plate is formed with a groove that is adapted to be engaged with the flat wire when said clamping plate abuts the flat wire tightly against the iron core.   
     
     
         6 . A coil winding method adapted for winding a conductive flat wire onto an iron core, said coil winding method comprising the steps of:
 placing the flat wire at a lateral side of the iron core;   operating a first clamping mechanism to abut the flat wire tightly against a lateral end of the iron core; and   operating a tension mechanism to provide a tension to the flat wire to stretch taut the flat wire, and rotating simultaneously the iron core and the first clamping mechanism to bend the flat wire with the flat wire being maintained to abut tightly against the lateral end of the iron core.   
     
     
         7 . The coil winding method as claimed in  claim 6 , further comprising the step of:
 moving the iron core and the first clamping mechanism away from the tension mechanism, and rotating simultaneously the iron core and the first clamping mechanism to further bend the flat wire with the flat wire being urged to abut tightly against another lateral end of the iron core.   
     
     
         8 . The coil winding method as claimed in  claim 7 , further comprising the step of:
 operating a second clamping mechanism to abut the flat wire tightly against the another lateral end of the iron core.   
     
     
         9 . The coil winding method as claimed in  claim 8 , further comprising the step of:
 separating the first clamping mechanism from the flat wire and moving the first clamping mechanism toward the tension mechanism.   
     
     
         10 . The coil winding method as claimed in  claim 9 , further comprising the step of:
 moving the iron core and operating a driving member of the tension mechanism to move a portion of the flat wire that abuts tightly against the lateral end of the iron core and that is bent in said step.
